Description:
------------
On the 'Operator precedence' manual page( http://www.php.net/manual/en/language.operators.precedence.php )
the => operator seems to be missing from the list. Its precedence might be obvious to some, or most, 
but I suppose it would be better if it is included in the php documentation.

P.S. I was going to write a comment on the manual page, but unless the developers don't consider it a bug, I won't proceed with posting it.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

Thank you for your quick action, but I'm not sure this is the correct precedence for that operator: 

 since '=>' and the ('or', 'and' and 'xor' ) operators 
can be used together, (through testing) I have found out 
that the precedence of the '=>' operator is between 
the 'or' operator and the ',' operator, 
and that it has no associativity. 

Please correct me if I'm wrong. 

 
(example:

var_dump(array('key1' => TRUE xor TRUE));
will yield: 
array(1) {
  ["key1"]=>
  bool(false)
}

, and:

var_dump(array(0 or  'key2' => TRUE));
will yield:
array(1) {
  [1]=>
  bool(true)
}

)
